Abstract (from CDS):

The Multipurpose InfraRed Imaging System (MIRIS) performed the MIRIS Paα Galactic Plane Survey (MIPAPS), which covers the entire Galactic plane within the latitude range of -3b≲+3 at Paα (1.87 µm). We present the first result of the MIPAPS data extracted from the longitude range of ℓ=96○ / . 5-116.°3 and demonstrate the quality and scientific potential of the data by comparing them with Hα maps obtained from the INT Photometric Hα Survey (IPHAS) data. We newly identify 90 H II region candidates in the WISE H II region catalog as definite H II regions by detecting the Paα and/or Hα recombination lines, out of which 53 H II regions are detected at Paα. We also report the detection of an additional 29 extended and 18 point-like sources at Paα. We estimate the E(B-V) color excesses and total Lyman continuum luminosities for H II regions by combining the MIPAPS Paα and IPHAS Hα fluxes. The E(B-V) values are found to be systematically lower than those estimated from point stars associated with H II regions. Utilizing the MIPAPS Paα and IPHAS Hα images, we obtain an E(B-V) map for the entire region of the H II region Sh2-131 with an angular size of ∼2.°5. The E(B-V) map shows not only numerous high-extinction filamentary features but also negative E(B-V) regions, indicating Hα excess. The Hα excess and systematic underestimation of E(B-V) are attributed to light scattered by dust.
